I vote to get Avid to put your synthesis into the Avid manual. It is great.

There is an argument that 60 frames per second of a lower resolution picture (720 lines vs. 1080 lines) is actually equal to or higher quality than less frames of the higher resolution. Despite where you fall on this argument, there is no denying that 60 FPS is better than 30 FPS for high action content like sports.
